TANNERS TOGGLE.

Patented J an. 13, 1914.

Application filed. May 8, 1913. Serial No. 766,427. 7

To all whom it may concern:

Be it known that I, JOSEPH D. CoUeHnIN, a citizen of the United States of America, and a resident of Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Tanners Toggles, of which the following is a specification.

This invention relates to devices for stretching leather to which has beenapphed a coating of patent leather preparat1on, and which it is desired to thoroughly dry while the leather is stretched on suitable frames. These devices are commonly known to the trade as single toggles.

Several forms of single toggles have heretofore been constructed but all of them are objectionable either on account of the expense or their inability to secure the cord thereof sufficiently to prevent it from sl1pping through the cross member formmg a part of said toggle.

The object of the present lnvention 1s to obviate these objections and produce an 1nexpensive device of this class in which the cord is securely clamped to the cross member and it consists in two wires twisted together to form the cross member with a cord clamped securely between sald wlres mtermediate their ends.

The invention further consists in cert-am novel features of construction and arrangement of parts which will befully understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents an elevation of a toggle embodying the principles of the present invention. Fig. 2 represents an elevation of a cord having a loop formed in one end thereof. Fig. 3 represents a perspective view of said cord showing a wire passed through its loop. Fig. 4 represents a side elevation of said cord showing two wires one through sald loop and another positioned parallel thereto at right angles to the crossing of said cord. Fig. 5 represent-s a plan view of the same.

' Fig. 6 represents a view similar to Fig. 1

with the wires twisted, and Fig. 7 represents a plan view of the completed toggle showing the cross member thereof formed of said twisted wires.

Similar characters designate like parts throughout the several figures of the drawmgs.

In the drawings, 10 is a cord or twine in which near one end is formed a loop 11, pertions of said cord in the formation of said loop crossing each other at 12. Through the loop 11 is passed a short wire 13 and outside of said loop 11 opposite and at right angles to said crossing 12 is positioned a wire 14 parallel to the wire 13 and of the same length. When the wires 13 and 14 have been thus positioned relative to the loop 11 the ends of both wires are seized and twisted tightly together as indicated at 15 in Figs. 1, 6, and 7, thereby clamping the cord or twine 10 so firmly bet-ween the wires as to absolutely prevent it slipping relative thereto. It is obvious that, in the twisting of the wires 13 and 14 they will form a plurality of bights or bends in the cord which will have the efiect of holding said cord in position even under the greatest strain. This makes a most efiective toggle which may be constructed at slight cost and will be sufficient to withstand any strain that it may be desired to give in the stretching of the leather to which it is applied.

One advantage of this device is that the cross member 15 being free from all projections is adapted to lie fiat upon the leather being stretched, and, moreover, only very small holes need to be punctured in the edge of the leather for the insertion of the cord 10. The cross member 15 being made of twisted wires has an uneven periphery which obtains a better grip upon the hide or leather while being stretched. When in operation the cord 10 is passed through a hole in the leather to be stretched and is secured to th usual stretching frame in any well known manner.

The many advantages of a toggle constructed as herein shown and described will be fully apparent without further description.

Having thus described my invention, I claim:

1. A new article of manufacture consisting of a cord and two metal members on opposite sides of an end thereof and twisted together.

2. A new article of manufacture consisting of two metal members twisted together with an end of a cord twice passed between said members and clamped thereby.

3. A new article of manufacture consisting of a cord having a loop formed in one end, a: wire inserted through said 100p, and

another Wire at right angles to and OlltSiClk? diate the ends thereof.

5. A new article of manufacture consist-- mg of two short wires of equal length twisted together from end to end and hav- Copies of this patent may be obtained 10; itf'cfajts' ea; 5 addressing the.

ing clamped between said wires the end of a cord of relatively greater length than said wires.

6. A new article of manufacture consisting of a plurality of metal members twisted together and a cord having one end thereof passed twice between said members and I clamped thereby.
